L = Blue V = Violet SB = Sky BlueR = Red G = Green LG = Light Green
P = Pink Y = Yellow GR = Gray
O = Orange
The first letter indicates the basic wire color and thesecond letter indicates the color of the stripe.
Example: L Y
L(Blue)
Y(Yellow)
[C] : The position of the parts is the same as shown inthe wiring diagram and wire routing.
[D] : Indicates the pin number of the connector.The numbering system is different for female
and male connectors.Example : Numbered in order
from upper left tolower right
Numbered in orderfrom upper right tolower left
Female Male
The numbering system for the overall wiring diagram isthe same as above
[E] : Indicates a Relay Block. No shading is used andonly the Relay Block No. is shown to distinguishit from the J/B.
Example : Indicates Relay Block No.1
[F] : Junction Block (The number in the circle is the J/B No.and the connector code is shown beside it).Junction Blocks are shaded to clearly separate themfrom other parts.
3C indicates thatit is insideJunction BlockNo.3
Example:
[G] : Indicates related system.[H] : Indicates the wiring harness and wiring harness
connector. The wiring harness with maleterminal is shown with arrows ( ).Outside numerals are pin numbers.
Female Male ( )
[I] : ( ) is used to indicate different wiring andconnector, etc. when the vehicle model, engine type,or specification is different.
